HEATING FOR-CED DRAFT.

SPECIFICATION forming part Of' Letters Patent N0. 523,598, dated July 24, 1894.

I Application filed November 14, 1893. Serial No. 490,913- (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS MANSON RY- MER-JONES, a subject of Her Majesty the Queen of Great Britain, residing at London, England, have invented a certain new and useful Improvement in Heating Forced Drafts and Ventilating Steamships, of which the following is a specification.

My invention relates to an improvement in the heating of forced drafts and ventilating steamships and consists in utilizing the waste heat from the funnels of steamers by means of a jacket placed around the funnel with a fan for forcing the draft through the furnaces, and with pipes leading from the different parts of the vessel into said jacket for ventilating purposes.

To clearly explain my invention reference is made to the accompanying drawings, in which- Figure 1 is longitudinal section of a portion of a steamship having my improvement applied thereto. Fig. 2 is a plan of the funnel valve and Fig. 3 is a longitudinal section of a portion of the funnel illustrating a modification.

Around the funnel a I arrange a casing b in connection with a fan 0 on one side, said pipe being provided with a flap valve e.

fan being driven by an engine or in any other suitable way While on the other side of the casing is a pipe at connected therewith salikd t some convenient point in the funnel casing is arranged a hit and miss valve f consisting of two perforated rings or plates fitting into the annular space forming the casing. This valve may be operated from the outside by means of a handle to open or close the passage through the casing. With a pipe g which leads to the furnaces.

When a forced draft is required the fan a draws a downward current of air through' the casing which passes over the heated surface of the funnel and at the same time draws the foul and heated air by means of the pipe The fan 0 connects -of the ship communicating therewith.

By braticing the jacket '5. e. by dividing it vertically bya partition h as shown in dotted lines Fig. 3 and connecting the pipe d to the casing on one side of same and the fan 0 to the other side the two drafts may be made to work, the one downward and the other upward at the same time. The valvee in the pipe d prevents any down cast of heated air passing into said pipe.

It will be evident that the casing 11 may be arranged only as a ventilating casing when a forced draft is not required and in that case the fan 0 may be dispensed with or the forced draft connection may be used alone without the ventilating connection.

What I claim is y In combinationthe funnel a provided with a casing 17, a partition dividing the casing, a ventilating pipe cl connected to the casing on one side of the partition and provided with a flap valve, and a fan connecting with the casing on the other side of the partition and adapted to draw heated air'from one side of the casing and deliver it to the fire, substantially as described. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

THOMAS MANSON RYMER-IONES.
